llVlPROVED BED-BOTTOM.

Specification forming part of Letters Patent No. 53,706, dated April 3,1866.

In the drawing herewith annexed, and form-v ing a part of thisspecification, A represents the bedstead, which is made in any of theordinaryforms. Within the bedstead is placed the bed-bottom, which iscomposed of two side pieces, F, and two cross-pieces, D D, which areattached to and connect the side pieces, F. Upon the cross-pieces D Dare a series of spiral springs, E. Directly upon the spiral springs E isa metallic spring, which extends from one side of the bed-bottom to theother, as seen at B B, and hold the spiral springs E in their properplaces.

C represents a series of slats running lengthwise with the bed andsecured upon the metallic springs BB, which form the top ofthebedbottom.

H represents ahorizontal metallic bar, which is placed at the head ot'the bedstead. At the outside ofthis bar is a dog and ratchet, h and andg, which are secured to the outer sides ot the bedstead. At the innerside of the bedstead and encircling the bar H are cogs a a.

b b represent rack-bars, which have teeth and mesh into the cogs a a.One rack-bar is attached to each side of the bed-bottom at the head.

N ear the foot ot' the bed-bottom is a small bar, c, which is secured tothe bedstead by means of a bracket d, said bracket extending a shortdistance beneath the side pieces ofthe bedstead.

It will be seen that this bed-bottom, being adjustable by means of thebar H, with the cogs a a and rack-bars b b, can be elevated or loweredat the head to suit, the dog and ratchet at the outer side securing' thesame in the required position.

The metallic springs B B, extending across the bed-bottom, not onlysupport the spiral springs E, but combine them and hold the same totheir proper places. At the saine time the pressure is divided betweenthe springs.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

l. The bar H, with cogs a a and rack-bars b b, when arranged in themanner and for the elevating or lowering the head ot'abed-bottom,substantially as and for the purposes speciied.

2. The bars D and bars F, with springs E, in combination with thesprings B B, and rails C, arranged substantially as and for the purposesherein set forth.

As evidence that Iclaim theforegoing I have hereunto set my hand in thepresence ot' two witnesses.
